On 42.2.
Yesterday, while driving on a highway at 65 MPH under NOAP, the dashboard display changed from AP showing the adjacent lanes to just showing our car (like when the car is parked). Then the dashboard displayed blacked out and didn't come back. The console display was still showing navigation - but wasn't updating - so I tried rebooting dashboard & console while the car was moving. Both displays stayed black for a much longer time than normal during a reboot - and when they did come back, we didn't get the LTE data service for minutes afterward.
After that, everything worked fine for the remaining 280+ miles of our drive.
